Special features
- Operating software
The operating program in this charger is executed with mutual links and communications with every
components to prevent any possible error, so it introduces the maximum safety. Especially, the charging
algorithm is so multifarious that you can select the best program to suit your requirement. And BC8DX has
a large LCD for showing various informations including charge/discharge graphs during the process.
- High-power dual output circuit
BC8DX employs the circuit that features two totally independent but identical high-power outputs which
are powered as much as 160watts each. As a result, it can charge or discharge up to 44 cells of
NiCd/NiMH or 16 series of Lithium batteries simultaneously. Furthermore, the twin-fan cooling system is so
efficient that can hold such a power without any trouble of running the circuit.
- Dual Individual voltage balancer for Lithium batteries
BC8DX has individual cell voltage balancers at both outputs. So it does not need any balancer separately
when charging Lithium batteries (LiIo/LiPo/LiFe) for voltage balancing.
- Balance individual cells on discharge
BC8DX also can monitor and balance individual cells of the Lithium battery pack during the discharge
process as well as ‘FAST’ and ‘STORAGE’ mode. If the voltage of any one cell varies abnormally, the
process will be stopped with the error message.
- Accept various types of Lithium battery
BC8DX can accept three types of Lithium batteries - LiIo, LiPo and LiFe. They have different
characteristics by their chemistry. You can select any one of them that you are going to process before the
job. For their specifications, refer 'Warnings and safety notes' section.
- Maximum safety
Delta-peak sensitivity : The automatic charge termination program works on the principle of the
Delta-peak voltage detection. (NiCd/NiMH)
Auto-charge current limit : When charging NiCd or NiMH at 'AUTO' current mode, you can set the upper
limit of charge current to avoid from feeding high current to the battery. This is very useful when charging
the low impedance and small capacity NiMH battery in 'AUTO' mode.
Capacity limit : The charging capacity always calculated by multiple of the charging current and time. If
the charging capacity exceeds the limit the process will be terminated automatically when you set the
maximum value.
Temperature limit : The temperature of the battery on charging or discharging will be raised by its
internal chemical reaction. If you set the limit of temperature the process will be expired forcibly when the
limit has been reached.
Processing time limit : You can also restrain the maximum processing time to prevent any possible
defect.
- Cyclic charging/discharging
Perform 1 to 10 cycles of charge>discharge or discharge>charge continually for battery refreshing and
balancing at both outputs.
- PC based analysis using USB communication
For technical expert, BC8DX offers PC based program can analysis the characteristic of the battery via
USB port. It shows a graph of voltage, current, capacity and temperature curves. It also shows the
individual voltage of each cell in the Lithium battery pack. This program can run on both outputs with
single USB link to PC.

Warnings and safety notes
Never leave the charge unsupervised when it is connected to its power supply. If any malfunction is
observed, terminate the process immediately and refer to the operating instructions.
Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. Do not drop it.
The circuit of the unit is designed to be powered by a 12V DC like car battery or similar DC power
supply.
The charger and the battery to charge or discharge should be set up on a head-resistant,
non-inflammable and non-conductive surface. Never place them on a car seat, carpet or similar. Keep
all the inflammable volatile materials well away from operating area.
Be sure to understand the information of the battery to be charged or discharged accurately. If the
program is set up incorrectly the battery can severely be damaged. Especially Lithium battery can
cause a fire or an explosion by over-charging.

To avoid short-circuits between the charge lead, always connect the charge cable to the unit first and
only then to the battery to be charged or discharged. Reverse the sequence when disconnecting.
Do not attempt to charge or discharge the following types of battery.
- Battery pack, which consists of different types of cell (including different manufacturers).
- Battery, which is already fully charged or just slightly discharged.
- Non-rechargeable batteries (Explosion hazard).
- Batteries that require a different charge technique from NiCd, NiMH, LiIo, LiPo, LiFe or Pb.
- Faulty or damaged battery.
- Battery fitted with an integral charge circuit or a protection circuit.
- Batteries installed in a device, or which are electrically linked to other components.
- Batteries that are not expressly stated by the manufacturer to be suitable for the currents the charger
delivers during the charge process.
-4-
Please bear in mind of checking the following point before charge operation.
- Did you select the appropriate program, which are suitable for the type of battery?
- Did you set up adequate current for charging or discharging?
- Lithium battery pack can be composed with parallel and series circuits mixed. You have to check
the composition of the battery pack carefully before charging.
- Are all connections firm and safe, or is there an intermittent contact at any point in the circuit?
Charging
A specific quantity of electrical energy is fed into the battery during charge process. The charge
quantity is calculated by multiplying charge current by charge time. The maximum permissible charge
current varies according to the battery type or its performance, and can be found in the information
provided by the battery manufacturer. It is only allowed to charge batteries at rates higher than the
standard charge current if they are expressly stated to be capable of quick-charge.
- Connect the battery to charge to output terminal of the charger using suitable charge lead. They are
red, positive(+) and black, negative(-). Since the charger may not detect the difference between the
internal resistance of the battery pack, cable resistance and connectors transfer resistance, the first
requirement, if the charger to work properly is that the charge lead should be of adequate conductor
cross-section. And also high-quality connectors (normally gold-contact type) must be fitted to both
ends.
- Refer to the information provided by the battery manufacturer regarding charging methods, and
verify the recommended charge current and charge time. Especially for Lithium batteries, you have to
follow the charge instruction provided by the manufacturer strictly.
- Do not attempt to disassemble the battery pack arbitrarily.
- You have to pay attention to verify the capacity and the voltage of the Lithium battery pack. It may be
composed of parallel and series connection mixed. In parallel link the capacity of the battery pack is
multiplied by the number of cells but the voltage remains same. That kind of voltage imbalance causes
a fire or explosion during charge process. We recommend you compose the Lithium battery pack in
series only.
Discharging
The typical purpose of discharge is to determine the residual capacity of the battery, or to lower the
voltage of battery to a defined level. When you discharge the battery you also have to pay attention on
the process same as charging. To avoid the battery becoming deep-discharged, set the final discharge
voltage correctly. Lithium batteries should not be deep-discharged to lower than the minimum voltage,
as this leads to a rapid loss of capacity or a total failure. Generally, you do not need to discharge
Lithium battery voluntarily.
- Some rechargeable batteries are said to have a memory effect. If they are partly used and
recharged before the whole charge is drawn out, they 'remember' this and next time will only use that
part of their capacity. This is a 'memory effect'. NiCd and NiMH batteries are said to suffer from
memory effect. They prefer complete cycles; fully charge then use until empty, do not recharge before
storage - allow them to self-discharge during storage. NiMH batteries have less memory effect than
NiCd.
- The Lithium battery prefers a partial rather than a full discharge. Frequent full discharges should be
avoided if possible. Instead, charge the battery more often or use a larger battery.
- The brand-new NiCd battery pack is partially useful with its capacity until it has been subjected to 10
or more charge cycles in any case. The cyclic process of charge and discharge will lead to optimize
the capacity of battery pack.
! Those warnings and safety notes are particularly important. Please follow the
instructions for a maximum safety; otherwise the charger and the battery can be damaged
violently. And also it can cause a fire to injure a human body or to lose the property.

- Chg. mode (Charge mode) : You can select a method of charging,
they are Normal, Balance, FAST.
Balance mode; This is for equalizing the individual voltages of
battery pack. The battery pack should have the individual cell
connector. Connect it to the individual port at the charger with a
suitable connection cable or adaptor that fits with the type of
connector of your battery pack. And also, you should to connect the
battery output plug to the output of charger. The internal processor of
the charger will monitor the voltages of each cell and controls the
charging current to equalize the voltage.
FAST mode; To charge the battery earlier, this program eliminates
certain term of CV range. Actually, the charging current will go to 1/5
of initial value gradually at the end of process, while the normal
charging goes to 1/10 at the end of CV term. The charging capacity
may be bit smaller than normal charging but the charging time can be
reduced.
- End curr. (End current) : Set the final charging current at
termination. The end current should be less than the initial
charge current.
Auto; The process will be terminated when the charging current go
to 1/10 of its initial value. Otherwise, the charge current will be
decreased until the designated value has been reached. (Auto,
60~500mA)
- Chk. time (Check time) : BC8DX recognizes the cell-count of
Lithium battery automatically and shows the counts at the beginning
of charge or discharge process to avoid from erroneous input by
user. But the battery which has been discharged deeply can be
perceived the cell-count incorrectly. The charger will work on the
cell-count anyway during the check time. But if the charger finds the
wrong cell-count at the end of check time, the process will be
terminated with an error message. To prevent the error, you can set
the time term to verify the cell-count by the charger. Normally, 10
minutes are enough to perceive the cell-count correctly. For the
battery of larger capacity, you may extend the time term. (5 ~ 250
min.)
! It is very important to know the exact type of battery to be charged, nominal voltage and
capacity. Not to know these facts is the reason why batteries are damaged and improperly
cared for. Read the battery’s label and instruction sheet carefully, or consult the battery
supplier to get those facts.
! For balance mode charge, BANTAM supplies some balance adaptors for various brands of
Lixx batteries in the market. The balance adaptor should be acceptable at this charger.
The suitable adaptors for single battery pack are;
Part no. EAC133: PolyQuest type, EAC134: Align type, EAC138: Kokam/Graupner type and
EAC139: FlightPower/ThunderPower type.
The suitable adaptors for balancing multiple battery packs are;
Part no. EAC153: PolyQuest type, EAC154: Align type, EAC158: Kokam/Graupner type and
EAC159: FlightPower/ThunderPower type.

'STORAGE' program for Lithium battery
This is for Lithium battery not to be used for long time. The program will determine to charge or discharge
the battery to a certain voltage depending on the voltage of the battery at its initial stage. The final voltage
are different from type of batteries, 3.75V for LiIo, 3.85V for LiPo and 3.3V for LiFe per cell. If the voltage
of battery at its initial stage is over the voltage level to storage, the program will start to discharge.

Safety programs for all types of battery
- Max. capa. (Maximum capacity) : You can define the maximum capacity which can be charged or
discharged by the form of a percentage of battery capacity set in the top of display. If full-charge has not
been detected for any reason, the charger limits the quantity of feeding energy by the value and terminates
the process as on the value is reached. If the battery manufacturer recommends to apply a partial charge
to battery before long-term storage, you can use this function also. This is a safety feature programmed to
protect the battery from over-charging or deep-discharging condition. (50 ~ 120%)
- Safety timer : When you start a charge process, the integral safety timer automatically starts running.
This is programmed to prevent over-charging or deep-discharging the battery, if the charger or battery is
proved to be fault. Or, if the termination circuit cannot detect the full-charging. The value for the safety
timer should be generous enough to allow the full-charging. (10 ~ 1380 min.)
- Safety temp. (Safety temperature) : This is a feature using temperature probe contacting the surface of
battery. The charger can monitor the temperature of battery being charged or discharged. Monitoring the
battery temperature can result in the most accurate full charges in addition to its voltage. The
recommended maximum values are 45~55C(113~130F) for NiCd, 43~52C(110~125F) for NiMH and
32~35C(90~95F) for Lixx. Once the battery reaches this temperature during the process, the program will
be terminated to protect the battery. If the battery reaches the temperature during discharge, the discharge
process will temporarily pause to allow the battery to cool down to a safe temperature. The discharge
process will automatically resume when the battery’s temperature drops about 4°C below the maximum
temperature setting. Set the maximum temperature at which the charger should allow the battery to reach
during charge or discharge process. (20 ~ 80C)

These batteries need to adopt different charge technique which is termed constant current(CC) and
constant voltage(CV) method. As the process starts, the CC phase will be committed first, in which the
charging current is maintained at a constant level until the battery reaches their final charge voltage. And
then, the CV phase will be initiated, in which the voltage is maintained at a constant level. At this point the
battery already has been charged about 80~90% full. The charging current will start to decrease until it
reached its 1/10 of starting amount. When the charging current reaches 1/10 of initial amount, the charger
will stop the charging process. The battery is virtually fully charged at this point.

! Cautions for NiMH batteries
- Do not allow NiMH batteries to over-heat. Using the battery cooler will prevent over-heating at
charge and discharge.
- Small size batteries like ‘AAA’, ‘AA’ and ‘A’ can safely be full charged at currents up to 1.0C.
Higher charge current can easily over-heat batteries and thus damage batteries.
- NiMH batteries have higher self-discharge rate compare to NiCd, so it is necessary to
recharge the battery immediately prior to use.
- Store NiMH batteries with some voltages remaining.

Milliampere(mA): The electric current, being amps(A) multiplied by 1000 and noted as 'mA'. So 2.0A is
the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the mA number by 1000. So 200mA
is the same as 0.2A. If a current value is below 1.0A, the LCD screen of the charger will still show the
current in amps, not milliampere. For example, a current of 600mA will be displayed as 0.6A, and a
current of 100mA will actually be shown as 0.1A.
Capacity,milliampere hours (mAh), and amp-hours (Ah): Charge energy stored by a battery is called
capacity, which is defined as how much current a battery can supply constantly over one hour of time.
Most hobby batteries are rated for capacity in 'mAh' or milliampere hours. A 650mAh battery can deliver
650mA of current for one hour (650mAx1hr = 650mAh). The batteries of very large capacity, such as
lead-acid(Pb) batteries, are usually rated in 'Ah' or amp-hours. A '12V 60Ah' car battery can deliver 60
amps of current for one hour (60Ax1hr = 60Ah).
Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;
-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a nominal
voltage of 9.6 volts (8x1.2).
-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a
nominal voltage of 11.1 volts (3x3.7).
-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have a nominal
voltage of 7.2 volts (2x3.6).
-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series will have a
nominal voltage of 13.2 volts (4x3.3).
If the nominal voltage of the battery is not printed on the battery's label, consult your battery
manufacturer or supplier. Do not guess the rated voltage of battery.
'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend charge and
discharge currents based on the battery 'C' rating. A battery's '1C' current is the same number as the
battery's rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C current value of
600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current value for a 3200mAh
battery would be 3200mA (3.2A).

Maximum circuit power chart
For the voltage of battery is more than 16V, the actual amount of charge current feeds to the battery
might automatically be limited, so not to exceed the charger's maximum rated charging power of 160
watts at an output channel. And also, for the battery having more than 5V, the discharge current delivered
to the battery might be limited by the maximum rated discharge power of 25 watts per output.
